Dewatering pumps are an essential tool for many construction, mining, tunnels, and other areas where water accumulation can be detrimental industrial applications. These pumps are designed to remove and drain away excess water.
A dewatering pump, also referred to as a water removal pump, is a mechanical device used to remove water from an area or structure. It operates by creating a pressure differential that forces water to flow from a low-lying area to a higher elevation or a designated drainage system. The primary purpose of a dewatering pump is to keep construction sites, mines, and other areas dry, allowing work to proceed efficiently and safely. Dewatering pumps are offered in a wide range of sizes and configurations to match various water removal applications.
There are various types of dewatering pumps available, each with its own unique characteristics and applications. The most common types include centrifugal pumps, submersible pumps, wellpoint systems, and vacuum-assisted pumps.
Centrifugal Pumps: These pumps use an impeller to create centrifugal force, which pushes water away from the pump and into a discharge pipe. Centrifugal pumps are widely used due to their high efficiency and ability to handle large volumes of water.
Submersible Pumps: Submersible pumps are designed to be fully submerged in water, making them ideal for dewatering applications in deep excavations or confined spaces. These pumps are highly efficient and can handle both clean and dirty water.
Submersible dewatering pumps are designed to operate while fully submerged in the water being pumped. The pump motor and internal components are sealed in a watertight casing that prevents water intrusion even when immersed.
Electric submersible dewatering pumps are typically lowered into wells or sumps. The pumped liquid cools the motor and no priming is required. The units sit at the bottom of the water source and pump water straight from the sump in a single lifting stage.
Submersible pumps push water to the surface through a long discharge pipe or hose connected above grade. They can continuously remove large water volumes when required to maintain very low or completely dry conditions. Submersible units provide an efficient dewatering solution for collecting leaked water from excavations, mines, pits, and holding ponds.
Wellpoint Systems: Wellpoint systems consist of a series of small-diameter wells connected to a vacuum pump. These systems are commonly used in areas with high groundwater levels and are effective in lowering the water table.
Vacuum-Assisted Pumps: Vacuum-assisted pumps utilize a vacuum to draw water into the pump and then discharge it to a higher elevation. These pumps are particularly useful in situations where high suction lift is required.
Choosing an appropriately sized dewatering pump for the intended application is critical for proper water removal. Key factors to consider when sizing and selecting pumps include:
